6.12.1 Power Supply Sequencing and Reset Timing

The AM273x device expects all external voltage rails and SOP boot mode select lines to be stable before NRESET is de-asserted (brought from VSS level to VIOIN level). Likewise external voltage rails should only be powered down after NRESET is asserted (brought from VIOIN level to VSS level).Figure 6-1 describes the device wake-up and power-down sequence.

Table 6-10 lists the timing values shown in Figure 6-1.

Table 6-9 Device Wake-Up Sequence Timing
NAME DESCRIPTION MIN TYP MAX UNIT
tPOWER_STABLE

Settling time after initial power supply turn-on after which device power nets are at valid, recommended operating conditions.

NRESET should not be de-asserted (brought from GND to VIOIN level) before all power pins are at recommended operating point.

See Recommended Operating Conditions for recommended operating conditions of all device power pins.

 0 ms
tRESET_DELAY

Delay after device power nets are at valid, nominal values, when NRESET can be brought from VSS to VIOIN level.

NRESET can be brought from VSS to VIOIN level anytime after power supplies are at recommended operating conditions.

 0 ms
tSU_SOP

Setup time for SOP signals to be sampled by the rising edge of NRESET.

Device is ready to sample SOP pin states anytime after power supplies are at recommended operating conditions.

 0 ms
tMSS_BOOT_START

Typical delay after NRESET rising edge before boot ROM to begins MSS code execution.

Value depends on whether device is operating directly from a crystal source or oscillator (REFCLK) source. Faster startup possible with the oscillator mode.

 0.5 7.0 ms
tRESET_POWER_DELAY

During power off events, delay after NRESET is brought from VIOIN to VSS level to when power pins can be powered off.

Device power pins can be powered off anytime after NRESET is brought to VSS level.
